Xfinity account link issue with Peacock - Error PPG_0017

Hello, I am receiving an error trying to link my Xfinity account to Peacock when activating the platinum member benefit.

This starting occurring after I moved my service to a new address, previously this was no issue. I believe Peacock still thinks that my account is linked to an Xfinity account associated with my previous service address but it's actually the same account. Is this a Peacock issue or an Xfinity issue?

This is very similar to what is discussed in this thread.
I would send a direct message about this as suggested there, however it appears my account does not have access to this feature as the chat icon is missing, see attached image.

I believe some sort of manual account benefit refresh may fix this issue.

Any advice is welcome to resolve this issue, thanks.
